Himel HDB9H Miniature Circuit Breakers (MCB) Series | 1-Pole, 10kA, C Curve, Industrial Range

Himel HDB9H 1-Pole 10kA C Curve Miniature Circuit Breaker (MCB) series represents the pinnacle of high-fault current protection for demanding commercial, infrastructure, and industrial electrical applications. Engineered to protect single-phase circuits against intense short circuits and thermal overloads, this heavy-duty range offers standard current ratings from 6A up to 63A. With an elevated 10,000A (10kA) breaking capacity certified under IEC/EN 60898-1, the HDB9H series ensures maximum safety and operational continuity where standard residential breakers cannot be code-compliant.

As a premium value brand within the Schneider Electric group, Himel designs the HDB9H series with advanced internal arc-chutes and ruggedized housings to absorb severe fault energies without failure. The versatile C-Curve tripping characteristic provides an optimized response profile—safely tolerating transient switching surges from industrial lighting arrays, IT servers, and small single-phase motor loads while providing instantaneous isolation during real faults. Designed for critical panel boards, this 18mm modular series features safe tunnel terminals, visual trip windows, and high mechanical endurance to support professional electrical contracting bids throughout Egypt.

Comprehensive Range Applications:

• 6A, 10A & 16A Models: Engineered for industrial lighting control, sensitive instrumentation, and automation PLC panels.

• 20A & 25A Models: Optimized for heavy-duty commercial server racks, administrative office circuits, and laboratory equipment.

• 32A & 40A Models: High-capacity single-phase protection for industrial ventilation fans, heavy pumps, and high-draw processing machinery.

• 50A & 63A Models: Heavy-duty single-pole incomers or sub-feeders for commercial building sub-panels.

Key Technical Advantages:

• 10kA Industrial Breaking Capacity: Safe interruption of high fault currents near main supply transformers.

• Schneider Engineering Architecture: Built under international quality protocols for robust electrical and mechanical endurance.

• C-Curve Surge Balance: Perfectly handles moderate inrush currents from modern commercial inductive loads.

• Advanced Safety Indicator: Visual window on the front face for clear, immediate circuit status verification.
